Acting US defence secretary Patrick Shanahan warns stability in the region is under threat, including the South China Sea

The United States will no longer “tiptoe” around Chinese behaviour in Asia, with stability in the region at threat on issues ranging from the South China Sea to Taiwan, acting US defence secretary Patrick Shanahan has said.

Shanahan did not directly name China when making accusations of “actors” destabilising the region, but went on to say on Saturday that the United States would not ignore Chinese behaviour, the latest acerbic exchange between the world’s two biggest economies.
